Hello, I have just bought a Mac and an Mbox 2 Pro. I have had some problems launching the program, and I just discovered that the version of Pro Tools that I bought (7.3) was made for Mac OS X 10.4 while I have OS X 10.5.2. Therefore I downloaded the 7.4 version for Mac OS X 10.5.3, and now I'm downloading Mac OS X 10.5.4. I just wonder if the Pro Tools version that I'm downloading is working for 10.5.4. Do you know?Please read my thread on the Chill Out Room: https://www.guitarmasterclass.net/guitar_fo...showtopic=18184for more information on the problem

Hm... I'm still at MacOS 10.4.11 running ProTools 7.4, so I'm not sure... but I think you need ProTools 7.4.2 if you use MacOS 10.5.x. Don't think it matter if you use 10.5.3 or 10.5.4 - you still need ProTools 7.4.2 since you've got Leopard.

The 7.4.2 upgrade is free for all 7.4 users, as far as I know

I installed 7.4.2, still won't work I wonder if I used the wrong authorization code as I have one for 7.3 and one for 7.4. I used the one on 7.4.
